A yellow pilot light means your furnace isn’t burning fuel cleanly. In New Cumberland homes, this is often caused by dust, rust, or poor ventilation around the burner. That yellow flame indicates incomplete combustion, which can release carbon monoxide. Turn the system off and have Honest Fix inspect it before running the furnace again.
Many New Cumberland homes near Ridge Avenue, River Avenue, and beyond the courthouse square rely on older basement furnaces. Those areas often face damp Ohio River air that encourages rust and corrosion in burners. With winter temperatures dropping quickly along the valley, sealed windows and tight basements limit airflow—making incomplete combustion more likely when the flame turns yellow.
Honest Fix technicians in New Cumberland frequently find clogged burner openings or dusty pilot assemblies. Low oxygen levels in enclosed spaces, especially in hillside homes near the state park, can also change the gas mix and alter the flame. Old gas lines or regulators may create pressure fluctuations, turning a steady blue flame into a weak, yellow one. These issues require immediate attention for safe heating.
A yellow flame signals incomplete combustion, which creates carbon monoxide (CO). CO is odorless and colorless, making it impossible to detect without proper testing. Because New Cumberland homes are tightly sealed during the winter, CO buildup can happen quickly. Honest Fix includes CO safety testing and burner inspection in every tune-up to keep indoor air safe.
A furnace tune-up and cleaning costs $109 and includes gas pressure adjustment, CO testing, and pilot cleaning. Diagnostic visits are $99. Every service includes Leo the Lion’s magnet—good for $25 off your next repair or tune-up.
No. A yellow flame means unsafe combustion and possible CO production. Shut it off and call Honest Fix.
Once a year, ideally in early fall, before heavy furnace use begins.
